Feature/feedback (#185)

* Remove automatic retry for scanLibraries as if something fails, it wont pass magically. Catch exceptions when opening books for parsing and swallow to ignore the file.

* Delete extra attempts

* Switched to using FirstOrDefault for finding existing series. This will help avoid pointless crashes.

* Updated message when duplicate series are found (not sure how this happens)

* Fixed a negation for deleting volumes where files still exist.

* Implemented the ability to automatically scale the manga reader based on screen size.

* Default to automatic scaling

* Fix an issue where malformed epubs wouldn't be readable due to incorrect keys in the OPF. We now check if key is valid and if not, try to correct it. This makes a page load about a second on malformed books.

* Fixed #176. Refactored the recently added query to be restricted to user's access to libraries.

* Fixed a one off bug with In Progress series

* Implemented the ability to refresh metadata of just a single series directly
